To all whom, t may con/cern.

Be it known that I, PERRY S. BAUER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Adhesive Plasters and Mode ofMaking Same, of which the following is a specification.

This invention relates particularly to rubber adhesive surgical plasterswhich are usually wound on spools in varying widths and lengths forcommercial use.

vHeretofore these plasters have been` generally made as follows: Awidestrip of fabric, generally from three hundred to four hundred yards inlength, is coated with adhesive and wound on a reel with the coated sideout and with separating-strips interposed between the windings toprevent contact. After the adhesive has dried sufficiently the materialis wound from the reel onto drums about'three feet in diameter andslightly lo'nOfer than the width of the materialfseveral drums vbeingrequired to hold the material on the reel. The rolls on the drums arethen cut transversely into small rolls of the widths desired forplasters, the drums being provided with a covering of wood or othersuitable material to prevent the cutting-tool from engaging the drumitself. It is necessary to thus wind the material from the rolls to thedrums in order that the rolls may be trimmed at the ends and subdividedtransverselyinto rolls of plaster' widths and also to bring the largequantity of material toa form suitable for the subsequent operations.The large roll on the drum may be divided into small rolls of equalwidths or of different widths. The small rolls are wound one at a timefrom the drums onto cylindrical blocks about a foot long, and from theseblocks the rolls are wound one at a time onto spools for commercial use.The small rolls are wound from the drum to the blocks in order tofacilitate handlin and winding on the spools. Alternate ro ls on thedrums arewound onto the blocks at first, so that considerable space willbe left on the blocks between the rolls. The spools used are completelybuilt up, the ends being soldered or otherwise made fast to thecylindrical parts that forml the core of the finished plaster-spools.Great care must be exercised in winding on the spools to keep the layersof the plasters even and make a symmetrical roll. This old mode ofmanufacture, which I believe is the general practice employed bymanufacturers of these plasters, is slow and expensive and involvesthree separate winding operations in which the material is wound uponitself-first on the drums, then on the blocks, and finally on thespools. The separating-strips are used only when the material is woundon the reel. The repeated winding of the material upon itself isobjectionable not only because of the time, labor, and expense involved,but partly because the adhesive is forced in and through the fabricduring the winding operations, and the plaster is thereby and otherwise,rendered less effective'for use.

My invention is designed to overcome these objections and to produce asuperior plaster by simplifying and improving the mode of manufactureand reducing the number of winding operations. To accomplish this, Iproceed, briefly, as follows: A paper tube is made fast on a revolublespindle and the material wound thereon from the reel in a plasterlength, the material being measured as it passes from the reel. The rollwith the paper tube inside is then removed from the spindle andsubdivided transversely by a knife or saw into plaster-rolls of properwidth. Then the cylinder of a spool is inserted in the paper tube ofeach plaster-roll to form a core of the complete device, and the ends ofthe spool are then secured on the ends of the cylinder to complete thespool.

In the accompanying drawings I have illustrated several steps in themanufacture of a rubber adhesive spool-plaster in accordance with myinvention, and referring thereto- Figure 1 shows the plaster wound onthe reel. Fig. 2 shows the material wound on the spindle. Fig. 3 showsthe roll removed from the spindle and one plaster-roll cut off.

Fig. 4 shows the spool-cylinder. Fig. 5 is a larger view showing thepaper tube and the s oel-cylinder in section and in place within t eplaster-roll. Fig. 6 is a transverse sectional view through a completespool-plaster.

The coated fabric 10 is wound upon a reel l1 in the usual manner, andfrom this reel the material is wound in a roll 12 on a paper tube 13,mounted on a spindle 14. The roll 12 is then removed from the spindlewith the palOO per tube inside thereof and subdivided by a cutting-tool,such as a saw 15, into plasterrolls 16 of required Width. v

The spool comprises a hollow cylindrical core 17 and the ends 18, theseparts being made separate from each other and constructed to be fastenedtogether after the plasterroll has been placed on the cylindrical core.For this purpose each spool end is provided with a hub 19, constructedto fit tightly in an end of the core, and they may be made to lit sotightly in the core that there will be no danger of their becomingdetached in use.

The roll 12 having been divided into plaster-rolls of proper Width, aspool-core 17 is inserted within the paper-tube 13 in each roll, asshown in Fig. 5, and then the spool ends are afliXed to the ends of thespool-core to form a complete spool-plaster, as shown in Fig. 6.

By my improved mode of manufacturing adhesive plasters theadhesive-coated material is Wound upon itself once only, and thiswinding corresponds to the final winding on the spool, according to themode of manufacture heretofore practiced. I thus eliminate from the modeof manufacture two windings of the coated material upon itself, andthereby avoid the ill effects due to repeated windings of the materialupon itself, which, as before mentioned, tends to force the adhesiveinto and through the fabric and otherwise renders the plaster lesseffective for use. My improved mode of manufacture in the mode ofmanufacture as heretofore practiced.

While my invention is, especially useful in connection with themanufacture of rubber adhesive surgical plasters, it can be obviouslyemployed with results of an equally-satisfactory character in connectionwith the manufacture of other plasters or like articles in which afabric or other foundation material is coated with adhesive.

What l claim, and desire to secure by Letters Patent, is-

1. As a new article of manufacture a spool adhesive plaster comprising atube, a plasterroll on said tube, a spool-core in said tube, anddetachable spool ends affixed to the ends of said core.

2. The mode herein described of making spool adhesive plasters whichconsists in winding the coated fabric into a roll upon a paper tube andthen subdividing the roll and tube into plaster-rolls of proper widths,then inserting the core of a spool in the tube 'Within the plaster-roll,and then afliXing the de-l tached ends of the spool to the ends of thecore.
